Darkness of two entangled fluorescing atoms inside a quantized standing wave cavity

摘要

We study the center-of-mass motion of two two-level atoms coupled to a single quantized standing-wave cavity mode. Using an effective one-dimensional model in the one-excitation case, we obtain a general expression of the dark states, the entangled two atom states which are almost immune against photon escape from the cavity. We analyze the effects of the atomic dipole-dipole interaction and of fluorescence emission from the single atoms on the time evolution of the atom-cavity system.
